Introduction to Stop Valve
A stop valve, also known as a globe valve, is a type of valve used for regulating flow in a pipeline. It operates by moving a disk or plug against the flow stream to control the amount of fluid passing through. Stop valves are widely used in various industries such as oil and gas, power generation, chemical processing, and water treatment due to their excellent throttling ability, tight shut - off, and reliable performance. They can be made from different materials like cast iron, carbon steel, stainless steel, and brass, depending on the specific application requirements.
